To all whom 22$ may concern:

Be it"knowirthat w film-1N h ICLEOWNAN MoMnnTi iin and lsl Romif'ibn, b'otli ubj ects of the Kin of Great Britain and name, aharesid nt,"restatemeor 2-12 ances for heating and lighting purposesot.

the class irrwhich a steam jet is fitted" concentrically within, and an air jet is 'fitted concentrically without, an oil jet and consists in the arrangement and construction of a series or a number of burners in a frame which is formed with two passages or ducts through. one of which: steam or other suitable fluid is conveyed to the ejector jets and through the other oil is conveyed to the oil jets of the burners which are formed with orifices or ports r'or the admission of air.

In order that our said invention and the manner of carryin same into efiect or practice may be properly understood we have hereunto appended three sheets of explana-v tory drawings in which- Figure 1 is an elevation of a hydro-carbon burner or appliance for heating and lighting purposes as constructed according to our improvements and Fig. 2 is a sectional plan view of same; the on the line 2-2 of Fig. 1; andFig. 3 is a sectional elevation at right angles to Fig. 1;

I the section being taken on the line of Fig. 2.

Referring to these drawings :In carrying these improvements into practice as applied to a steam boiler or like furnace we construct a frame 1 into which we lead a pipe 2 fitted with a regulating valve or cook (not shown) through which would be fed, by the suction action of the jets which will be hereinafter more particularly referred to, a suitable oil or hydrocarbon which would flow into a duct or receiver 3 common to a series of burners 4. A similar pipe fitted with a valve, (not shown) would lead high pressure steam, from a boiler or other source of supply, or it may be heated air, gas or other suitable fluid or a combination of these, to a similar duct or receiver 6 in the "frame 1 common to the series of burners 4.

section being taken Patented Nov. l,

Each burner 4: of the series has an oil or fluid cup or 1i e"chamber7"cc ntrolled by a valves whiclris fed 'from tlie oil duct id int re framc lcoinnion than and "theslteam i ther" highly heated fluid pass'es from the "duct 6 commdn to 'all tlirougha valve Qto a trapping oli er nbierl0, which is p emb y fit 'e i verhi i s wh n e t' trap any depositdwhich are removed through a'removablplufg lL The steam or fluid siipplv' in passing from' the ante "(3 to the"trapp'ing chamber lllpasses through a coil of piping 12 on which the flame from the burner 4' impinges 'so as to superhea't sameto a temperature of say about 1000 degre es Fahrenheit.

From the trapping chamber the superheated steam or fluid passes to a central nozzle or steam jet 13 which acts as an injector or ejector and draws the oil or hydrocarbon from its annular chamber 7 surrounding said central nozzle 13 through an annular aperture 14 in a thin stream. into a nozzle or oil jet 15 leading into a passage or air jet 17 formed in a cap or burner 1-. A series of ducts 19 are formed in the cap 4: so that atmospheric air will be drawn into the passage 17 by the vapor mixture issuing from the jet 15.

The jet 15 extends some distance into the passage 17 and the jet 13 some distance into the jet 15 in order that the air will be drawn in through the ducts 19 and the oil from the storage tank situated below the level of the apparatus into the jet 15 through the chamber 7.

The introduction of the air into the passage 17 (Fig. 3) near the issuing vapor mixture enables the flame to burn from near the mouth of the jet. By this arrangement all or any number of burners may be used or isolated to suit the heat requirements of the furnace.

The frame 1 may be fitted with a cover or casing 16 fitted with a hinged or removable door or doors for access to the appliances.

What we claim as our invention and desire to secure by Letters Patent, is

1. A burner consisting of a nozzle having an air passage leading thereto; a second nozzle of smaller diameter than and extending into the first nozzle, said second nozzle forming a closure for the bottom of the first nozzle and having an oil passage leading into its inner end; a third nozzle having a portion of smaller diameter than and leading part way into the second nozzle; a cap surrounding the lower portion of the third nozzle and forming a trap therefor; with a steam conduit communicating with the trap.

A burner consisting of a nozzle having an air passage leading thereto; a second nozzle of smaller diameter than and eX- tending into the first mentioned nozzle, said second nozzle forming a closure for the bottom or" the first nozzle and having an oil passage leading into its inner end: a third nozzle having a portion of smaller diameter than and leading part way into the second nozzle; a cap located directly below the lower portion of the third nozzle and forming a trap therefor; with a steam conduit communicating with the trap.

3. An appliance for heating and lighting orne 4s purposes consisting of a supporting frame having an oil duct and a steam duct; a plurality of burners supported by said frame and each including an oil nozzle, a steam nozzle and an air nozzle; with a plurality of heating coils on said frame and each having one end in communication with the steam duct, said frame having a plurality of ducts respectively connecting the oil ducts with the oil nozzles and also having passages respectively connecting the heating coils with the steam nozzles.

In testimony whereof, we have signed our names to this specification, in the presence of two subscribing witnesses.
